Review why you still sell expired product?

To be honest, i experience working in this company. It was a nice experience to know all the product from Australia, Kuala Lumpur and Philippine. The salary also quite nice, unfortunately i resign because i don't want to working with unhonesty people that STILL SELLING EXPIRED product by telling the customer. Whom asking about the product that their want to bought doesn't have any expired date and then you just said to the customer with confidently that product didn't have expired date because it was 12 month upon opening. Like seriously? eventhough the product already expired 2 year, 1 year ago but you STILL SELL IT TO THE CUSTOMER?. This is a fact, because not only me the local worker who been working in this company complaint about this. It not good for the company and the customer if you still doing like this(selling the expired product). Sorry i have to do this because i still got a text from the customer telling me about this(expired product). Sincerely from your ex worker.
